Compiled by the Lord of Evil himself, The Adventure Time Encylopaedia is the first official guide to the show's beloved characters and world. Matching the playful, subversive tone of the series, the Encyclopaedia includes everything anyone will ever need to know about the Land of Ooo and its inhabitants - secret lore and spells, fun places you should visit, what to eat and not to eat, plus "marginalia" and doodles by Finn, Jake, and Marceline. Fans of all ages will love this side-splittingly funny, complex, and intricate love letter to the series.
